Abstract

There is agreement regarding the fundamental role of transaction costs in determining currency options market efficiency. However, the estimation of transaction costs in this relationship is controversial. In this study, a bootstrapping approach is adapted to decompose the error term of the put-call parity regression analysis in order to estimate transaction costs. The currency option market is more than 95 percent efficient with the estimated transaction costs. This robust transaction cost calculation will be valuable to traders and researchers as it eliminates dependence on crude proxies for transaction costs.
